Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of double-sided adhesive tapes, and more specifically to a double-sided adhesive tape for PVC floors. Background Art
[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, with elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive evenly coated on the above base material. It consists of three parts: base material, adhesive, and release paper (film) or silicone paper. PVC flooring is a very popular new type of lightweight floor decoration material in the world today, also known as "lightweight flooring", and is widely used.
[0003] In the prior art, a patent document with publication number CN206232651U provides a double-sided tape for adhering PVC floors. The device has strong peeling force and high adhesion by arranging a first acrylate adhesive layer on one side surface of the PET layer, arranging a peeling adhesive layer on the other side surface of the PET layer, arranging a second acrylate adhesive layer above the first acrylate adhesive layer, and arranging a release paper layer on the second acrylate adhesive layer.
[0004] Although the device has many beneficial effects, the following problems still exist: when the temperature changes greatly during use, steam bubbles may appear at the joint of the tape and the object, resulting in a decrease in the adhesion between the tape and the object; during use, it only relies on a single adhesive layer to adhere to the outside, which is not strong enough and needs to be improved. In view of this, we propose a double-sided tape for PVC floors. Utility Model Content

[0014] 3. Beneficial effects
[0015] Compared with the prior art, the advantages of the present invention are:
[0016] The utility model stores the water vapor generated when the temperature difference changes too much by opening multiple cavities in the PET substrate, and disperses the water vapor into the external air through the air holes opened on the surface of the heat-resistant layer. At the same time, the excessively high temperature will cause thermal expansion and contraction, and the multiple rubber strips on the upper part of the solid soft rubber layer will expand and squeeze into the cavity, so as to prevent the deformation of the solid soft rubber layer caused by the thermal expansion and cause the adhesion performance to decrease.
[0017] Secondly, by arranging multiple coating capsules inside the adhesive body, when using double-sided tape, external force presses to rupture the coating capsules, and the hardener filled in the coating capsules flows out and reacts with the adhesive body to harden, thereby improving the adhesion. The utility model has a compact and reasonable structural design, strong high temperature resistance, better adaptability to temperature changes, and strong adhesion.

[0027] See also Figure 1-5 ,The utility model provides a technical solution:
[0028] A double-sided adhesive tape for PVC flooring comprises silicone paper 1, a release agent layer 2 is fixedly arranged at the bottom of the silicone paper 1, an adhesive layer 3 is fixedly arranged at the bottom of the release agent layer 2, a PET layer 4 is fixedly arranged at the bottom of the adhesive layer 3, the PET layer 4 comprises a heat-resistant layer 401 fixedly arranged at the bottom of the adhesive layer 3, a plurality of air holes 402 are provided on the surface of the heat-resistant layer 401, a PET substrate 403 is fixedly arranged at the bottom of the heat-resistant layer 401, a plurality of cavities 404 are provided inside the PET substrate 403, a solid soft adhesive layer 405 is fixedly arranged at the bottom of the PET substrate 403, a plurality of adhesive strips 406 are fixedly arranged on the upper part of the solid soft adhesive layer 405, a polyethylene film 5 is fixedly arranged at the bottom of the solid soft adhesive layer 405, another adhesive layer 3 is fixedly arranged at the bottom of the polyethylene film 5, and a tape shaft 6 is provided at the bottom of the other adhesive layer 3. The PVC floor is adhered to the desired object through the adhesive layer 3, and the moisture vapor generated when the temperature difference changes too much is better stored and volatilized through the air vents 402 and the cavity 404, thereby improving the high temperature resistance of the double-sided tape used for the PVC floor. When the surface temperature of the PVC floor is too high, the adhesive strip 406 is squeezed into the cavity 404 to prevent the solid soft adhesive layer 405 from being deformed due to thermal expansion, which leads to a decrease in adhesion performance. The polyethylene film 5 is used to achieve the purpose of waterproofing and insulation.
[0029] Specifically, the silicone oil paper 1 includes a base paper 101 fixed on the top of the release agent layer 2, a coating film 102 fixed on the top of the base paper 101, and silicone oil 103 fixed on the top of the coating film 102. The coating film 102 and the silicone oil 103 prevent the base paper 101 from being too firmly adhered to the adhesive layer 3, and the double-sided tape is not easy to be peeled off when used.
[0030] Furthermore, the adhesive layer 3 includes an adhesive body 301 fixed on the top of the PET layer 4, a plurality of metal salts 302 fixed on the surface of the adhesive body 301, a plurality of coating capsules 303 fixed inside the adhesive body 301, and a hardener filled inside the coating capsules 303. The metal salts 302 improve the water resistance of the adhesive body 301, and the coating capsules 303 are ruptured by external pressure, and the hardener filled inside the coating capsules 303 flows out and reacts with the adhesive body 301 to harden, thereby improving the adhesion and making the double-sided tape more firmly bonded to the PVC floor.
[0031] It is worth noting that the material of the adhesive body 301 is acrylic ester. Acrylic ester is used to improve the required stickiness of the double-sided tape used for PVC floor.
[0032] It is worth noting that the size and position of the plurality of vent holes 402 match the cavity 404, and the position of the plurality of cavities 404 matches the rubber strip 406. Through the vent holes 402 and cavities 404 that match in size and position, the moisture vapor stored in the cavity 404 can be transferred to the air through the vent holes 402.
[0033] In addition, the widths of the silicone paper 1, the release agent layer 2, the adhesive layer 3, the PET layer 4, the polyethylene film 5 and the tape shaft 6 are all the same, and another adhesive layer 3 is directly attached to the outer wall of the tape shaft 6, and then they are stacked and wound in sequence. By stacking and winding in sequence, the double-sided tape can be more effectively retracted and released, making it more convenient to construct on the PVC floor.
[0034] Working principle: When the device is needed to bond the PVC floor, stick the bottom surface of the adhesive layer 3 on the PVC floor, manually peel off the silicone oil paper 1, and prevent the bottom paper 101 from being too firmly bonded to the adhesive layer 3 through the coating film 102 and the silicone oil 103. Place the object to be bonded on the top of the adhesive layer 3, press hard to break the coated capsule 303, and the hardener filled in the coated capsule 303 flows out and reacts with the adhesive body 301 to improve the adhesion and make the object more firmly bonded to the PVC floor. When the temperature difference changes too much, the moisture vapor generated is stored in the cavity 404, and the moisture vapor is transferred to the air through the air vents 402 that match the position and size of the cavity 404. When the surface temperature of the PVC floor is too high, the rubber strip 406 squeezes into the cavity 404 to prevent the deformation of the solid soft rubber layer 405 caused by thermal expansion, which leads to a decrease in adhesion performance. The polyethylene film 5 is used to achieve the purpose of waterproofing and insulation, and the adhesive body 301 made of acrylic acid improves the adhesion.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
